Abstract: The invention relates to a method for providing an indication of movement from a sensor signal from a position transmitter (9), wherein the indication of movement indicates a speed of movement, wherein the sensor signal from the position transmitter (9) generates an edge following a movement via a particular path range having the following steps:—a pulse duration (dT) is ascertained (S1) as the interval of time between the last two provided edges of the sensor signal;—depending on whether a period which corresponds to the pulse duration (dT) has elapsed since the last provided edge of the sensor signal, an indication which is dependent on the pulse duration (dT) or an indication which is dependent on the period since the last edge of the sensor signal is provided (S4, S6) as an indication of movement.

Abstract: A signal scaling circuit for accurately reducing the effective amplitude of an input signal by a rational factor N/M, where N and M are integers and N<M, is disclosed. An input, reference, bias and output node as well as control circuitry are selectively coupled to M switched capacitor circuits such that N/M scaling may be achieved. Cooperation between the M switched capacitor circuits and the control circuitry divides the M switched capacitors circuits into subsets of N and M?N switched capacitors, respectively. Each subset is then selectively coupled to an input, reference and/or bias signal to produce an output signal having as one of its components an N/M portion of the input signal. Error reduction in the scaled signal is achieved by shuffling the switched capacitor circuits populating each subset after selected time intervals.
